Clean typing and DRY

Adopt a “type-correct, DRY, and clean” coding style.

Rules: 1) Make type hints compile and be precise

• If you use Dict, List, Union, etc., import them from typing (or use built-in dict/list where appropriate).
• Initialize typed containers explicitly (e.g., intention: Dict[str, Union[str, List[str]]] = {}) to avoid ambiguous types.

2) Remove unused assignments and dead code

• Don’t keep variables that are never used; don’t leave commented-out behavior in committed code—fix properly or remove.

3) Avoid redundant abstractions/config branches

• Don’t add wrapper classes when the base type already covers the functionality.
• Don’t redeclare abstract methods in a subclass if they’re already declared in the parent.
• Centralize config flags once (e.g., read from config/getter) and branch using that single value.

Example (typing + unused-code cleanup):

from typing import Dict, List, Union

def parse_intent(text: str) -> Dict[str, Union[str, List[str]]]:
    intention: Dict[str, Union[str, List[str]]] = {}  # typed and initialized
    # ... parse JSON, fill intention ...
    return intention

Example (DRY via config flag):

def explore(..., graph_store):
    similarity_search_enabled = graph_store.get_config().similarity_search_enabled
    if similarity_search_enabled:
        # do embedding/search logic
        pass
    # else: fall through

Enforce these checks in review and via tooling (lint/type checker) so style remains consistent and code stays maintainable.
